Carpenter Ant

APPEARANCE: Among the largest ants, from one-fourth to three-eighths inch long; most common species are black, but some have reddish or yellowish coloration; workers have large mandibles.
HABITS: Normally nest in dead portions of standing trees, stumps or logs, or burrow under fallen logs or stones; invade homes in search of food; nests inside homes can do great damage; hollow out “galleries” in wood that are so smooth they appear to be sandpapered.
DIET: Do not eat wood; will feed on nearly anything people eat, particularly sweets and meats; also feed on other insects.
REPRODUCTION: Queen lays fifteen to twenty eggs the first year, and up to thirty eggs the second year; eggs complete their life cycle in about sixty days; worker ants can live up to seven years, while a queen may live up to twenty-five years.
OTHER INFORMATION: All kinds of houses, regardless of age or type of construction, are vulnerable to infestation and damage by carpenter ants; very difficult to control; colonies can contain up to three thousand workers.
